Lunyu XI. 10. (277)

Confucius vindicates his great grief for the death of Hûi.
1. When Yen Yüan died, the Master bewailed him exceedingly, and the disciples who were with him said, "Master, your grief is excessive!"
2. "Is it excessive?" said he.
3. "If I am not to mourn bitterly for this man, for whom should I mourn?"

Legge XI.9.

When Yen Yuan died, in weeping for him, the Master showed under sorrow. His followers said, 'You are showing undue sorrow.' 'Am I? Yet if not for him, for whom should I show undue sorrow?'
